CMAKE – How to properly copy static library’s header file into /usr/include?

A better way for newest cmake version is to use target’s PUBLIC_HEADER properties.

project(myproject)

add_library(mylib some.c another.c)
set_target_properties(mylib PROPERTIES PUBLIC_HEADER "some.h;another.h")
INSTALL(TARGETS mylib 
        LIBRARY DESTINATION some/libpath
        PUBLIC_HEADER DESTINATION some/includepath
)

Some ref:

PUBLIC_HEADER

CMake install command
