svn commit: r472575 - in head/devel/cpp2py: . files

[Adriaan de Groot]

For completeness, I'll throw in an explanation of "correct cmake file paths" 
(which Yuri is correct in using).

CMake looks for modules in various places. Many CMake-based software projects 
(and some others) install modules to help CMake find those pieces of software 
-- for consumers of that software, for instance.

The CMake port itself installs stuff into ${LOCALBASE}/share/cmake, and in 
particular (normal settings), /usr/local/share/cmake/Modules are where the 
modules-shipped-with-CMake live.

Most other software installs to /usr/local/lib/cmake/ (no extra Modules/). The 
"big" consumers of CMake, KDE and Qt, but also small stuff like yaml-cpp, 
install their CMake modules there.

For CMake itself it doesn't matter: it searches many places for modules, see 
e.g. cmake --help-command find_package .

I guess on FreeBSD we could say we have a preference for keeping share/cmake 
as "the place for CMake itself" and lib/cmake as "the place for third-party 
modules". So thanks for tidying this up, Yuri.

(fwiw,  pkg which /usr/local/share/cmake/Modules/* | grep -v 'package cmake-3' 
tells me there's some leakage; not enough to go an update packages Just 
Because, but something to keep in mind if touching a port anyway)
