add_custom_command is rather used for operations performed during build phase
(which is completely separate off packaging)
You could create hgHash.txt during packaging by using install(SCRIPT) command:
install(SCRIPT hgHash.cmake)
install(
FILES hgHash.txt
DESTINATION yourapp
)
Hypothetical hgHash.cmake would be quite straightforward:
message(STATUS "Getting hg hash")
execute_process(
COMMAND hg --debug id -i
OUTPUT_FILE hgHash.txt
)
That would create hgHash.txt unconditionally during each cpack/make
install/cmake -P cmake_install.cmake invocation
