Are you on Linux by any chance? There is no install target for Linux by design: https://github.com/jiixyj/epoll-shim/blob/master/CMakeLists.txt#L47

The only reason to build this project on Linux is for running the test suite in order to verify how the different system calls in the epoll family behave natively.

my bad, i am sorry.
i try to use libei. then they ask to use epoll-shim
https://gitlab.freedesktop.org/libinput/libei/-/blob/main/meson.build#L77`

...
dep_epoll = dependency('epoll-shim', required: false)
...

even though required: false by mean optional *maybe

is it safe to me ? to comment this line, and go forward make install
so epoll-shim can found by env: pkg-config and cmake ?

If you are running Linux, there is no need for epoll-shim at all. This is why there is the required: false in dependency('epoll-shim', required: false). On Linux, epoll-shim must not be found, actually.
