The problem is that you add the GIT variables as compile time defines,
which means that after every commit you will have different compile command
lines, which trigger recompilation of whole project because you have used
add_definitions.
You should instead write those GIT variables in a file, like this:
file(WRITE ${CMAKE_BINARY_DIR}/git_version.h.in "
#define GIT_SHA1 \"@GIT_SHA@\"
#define GIT_TAG \"@GIT_TAG@\"
#define GIT_LOCAL_CHANGES \"@GIT_LOCAL_CHANGES@\""
)
configure_file(${CMAKE_BINARY_DIR}/git_version.h.in
${CMAKE_BINARY_DIR}/git_version.h @ONLY)
Make sure you have ${CURRENT_BINARY_DIR} as part of your target's include
directories. And then somewhere in your code do an #include "git_version.h".
Cheers,
Cristian.

[CMake] New version forces rebuild all?
I have cmake project, I usuall call "cmake ." followed by make. Now I have installed cmake 3.12.3 (was impossible install by apt-get) I have following problem: If I change one *.cpp file, in most cases make rebuilds all *.cpp files, not related to this file. Sometimes is ok. -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
