我想用 CMake 生成和编译 Visual Studio projet 我需要从构建中排除单元测试文件。 有没有办法做到这一点？

Question

My project contain unit testing file I want to excludes from the compilation process. I want to modify the .vcxproj Visual Studio file with CMake. What could be the possible solutions of my issue ?

set_source_files_properties(BankTestCase_1.h PROPERTIES VS_DEPLOYEMENT_CONTENT 0)

set_source_files_properties(BankTestCase_1.h PROPERTIES EXCLUDE_FROM_BUILD 1)

Answer 1

First off, you don't modify a .vcxproj file. CMake generates one. Each time you invoke cmake, a new project file is generated. You have to generate it correctly.

CMake has already a function defined just to add tests. It's calledadd_test

It work by specifying a name then a command or executable target:

add_executable(my_test_exe testsrc1.cpp testsrc2.cpp)
add_test(NAME MyTest COMMAND my_test_exe)

If you also want to not compile the test files in your main project, simply don't add them to your main target:

add_executable(main_project
    src1.cpp
    src2.cpp
    src3.cpp
    src4.cpp
    # srctest1.cpp # not added
    # srctest2.cpp # not added too.
)

Also, I notice that you want to remove header files from compilation. Header files are not supposed to be compiled at all. You should not add them to your target.

If you used globs to add all source files, then you can always remove it from the glob list:

list(REMOVE_ITEM globbed_files file/to/be_excluded.cpp)
