Since a comma is used to separate the list and the value, the listĬannot itself contain a comma. Must not contain any commas if that generator expression expects something toīe provided after the list. In each of the following list-related generator expressions, the list List() command, providing the same capabilities, but in Most of the expressions in this section are closely associated with the Same behavior as string(MAKE_C_IDENTIFIER). $ ¶Ĭontent of string converted to upper case. String Transformations ¶ $ ¶Ĭontent of string converted to lower case. For example, the followingĮvaluates to 1 if $ is any of BAR, Bar, bar, etc.ġ if v1 is a version greater than or equal to v2, else 0. For a case-insensitive comparison,Ĭombine with a string transforming generator expression. String Comparisons ¶ $ ¶ġ if string1 and string2 are equal, else 0. Other more specific comparison types are documented in their own separate This section covers the primary and most widely used comparison types. Primary Comparison Expressions ¶ĬMake supports a variety of generator expressions that compare things. The result of the expression isĠ if condition is 1, else 1. If allĬonditions evaluate to 0, the whole expression evaluates to 0. Where conditions is a comma-separated list of boolean expressions.Įvaluates to 1 if at least one of the conditions is 1. The whole expressionĮvaluates to 1 if all conditions are 1. Where conditions is a comma-separated list of boolean expressions,Īll of which must evaluate to either 1 or 0. The common boolean logic operators are supported: $ ¶ $: - DENABLE_SOME_FEATURE > Logical Operators ¶ Information specific to each build configuration. The enable_testing() command will cause a global test target to be defined, which would then clash with the one you’ve tried to define in the add_executable() call.Generator expressions are evaluated during build system generation to produce That target name is reserved for CMake’s own use. I should also mention that you should not call any targets you define “test”. That may be feasible for smaller projects, but for large projects with many executables (including test executables), that may not be appropriate. Many projects dump all DLLs and executables in the same output directory so that their users don’t have to deal with it. How you run things is something CMake can’t control, so it’s up to you to get that right. Either the DLL has to be in the same directory as the executable, or it has to be found in one of the directories specified by the PATH environment variable. When running the executable, that’s a different story. Sorry it has taken me so long to reply here, but are you talking about building or running your executable here? Building it shouldn’t require you to force the DLL for mdp_opt to be in the same directory as the test executable. What is more important is that with this change, it only works if I copy the file mdp_opt.dll from build/圆4-debug/mdp_opt to build/圆4-debug/test. I halfway understand why, but let’s forget that. post-build), what is the preferred way to deal with this in a cross-platform way? So if the answer is that this somehow does not work and that some manual copying is needed (e.g. That I intend to link the output associated with the target mdp_opt with the test executable? Also, in my reading of the above resource, my understanding is that the executable will convert to a path? Anyhow? Because CMake handles all the various platformĭifferences and paths on the project’s behalf, using a CMake target name is generally the When generating the linker command, including supplying any prefix or suffix to the file CMake will convert this to a path to the built library Just the library name without a path, usually also without any platform-specific file name.A path to a library, usually specified as an absolute path.Each library listed can be one of the following: Property INTERFACE_LINK_LIBRARIES is supported. It is initiallyĮmpty when the target is created and it supports generator expressions. This target property holds a list of all libraries the target should link to directly. In the book “professional CMake”, I read ( emphasis mine): I can do that - it is not a problem - but I don’t understand why? When it is marked SHARED (as in above), I need to add: This works fine if the library is marked STATIC (instead of SHARED as above). Target_link_libraries(test PRIVATE mdp_opt) I create a shared library like so:Īdd_library (mdp_opt SHARED librarycomponent.cpp) I am trying to figure out how CMake is supposed to work for shared libraries.
