Opened this issue · 2 comments

Adding a new git tag does not force a re-configure if cmake variables with git_get_exact_tag
git_get_exact_tag(GIT_TAG)
if(NOT GIT_TAG)
set(GIT_TAG "")
endif()
configure_file(${CMAKE_CURRENT_SOURCE_DIR}/gitinfo.cpp.in ${CMAKE_CURRENT_BINARY_DIR}/gitinfo.cpp)
Some files:
gitinfo.h
extern const char g_GIT_TAG[];
gitinfo.cpp.in
#define GIT_TAG "@GIT_TAG@"
const char g_GIT_TAG[] = GIT_TAG;

Hmm. Is there a file with a known location that we can watch to trigger a re-configure?

I suppose you could check for changes in .git/refs/tags
