Not a CMake expert but I looked at the code on github and it seems that
icinga2 uses its own copy of GNUInstallDirs that does not depend on
CMAKE_INSTALL_MANDIR. (See lines 169 to 183 in
third-party/cmake/GNUInstallDirs.cmake)
CMake comes with GNUInstallDirs and that one works as expected.
I suggest that you remove third-party/cmake/GNUInstallDirs.cmake so
that the package uses the one that comes with CMake and test if that
works. (I don't have a mac to try on)
