@DaanDeMeyer: Yes, my bad. Fixed submitted. Thank you!
@DaanDeMeyer: Thank you. I have updated the package updating to REPROC++ and REPROC_EXAMPLES.
In 3.0.0, REPROCXX got renamed to REPROC++. Also, REPROC_BUILD_EXAMPLES has been renamed to REPROC_EXAMPLES.
@DaanDeMeyer: Thank you for the suggestions. I have updated the package with them.
I've released reproc 2.0.0. Since the C++ support is now a separate library and doesn't affect the C library in any way, I propose to enable REPROCXX so users can depend on the C++ support as well.
It might also be a good idea to replace the mv command from lib64/ to lib/ by specifying the CMake option CMAKE_INSTALL_LIBDIR=lib. This way, CMake puts the library files in lib/ instead of lib64/ when installing reproc which removes the need for the mv command after installing.
REPROC_INSTALL is also enabled by default now so it can be removed from the PKGBUILD.
