License

Hi,

would it be possible to put this repository under a specific license? I would like to include the cmake file in my repository, but without a license, that doesn't seem to be allowed.

Thanks

Could not find compiler "" error when using with CMake with the Xcode generator on macOS

Hey!

I've put together a minimal example in a repo to show what's happening:
https://github.com/phraemer/reimagined-octo-guacamole

Probably just me doing something wrong but I couldn't figure it out yet.

See the error here:
https://github.com/phraemer/reimagined-octo-guacamole/runs/2213566880?check_suite_focus=true#step:4:64

Any ideas?
Let me know if I can help in any way

thanks!
James

Increase minimum CMake version to 3.5

CMake are going to drop compatibility with < CMake 3.5 and are already printing warnings in builds with 3.27

https://cmake.org/cmake/help/latest/release/3.27.html#deprecated-and-removed-features

Can we have a new release with the minimum version raised to at least 3.5 please?
Thanks.

CMakeLists.txt:

if (USE_CCACHE)
    CPMAddPackage (
        NAME Ccache.cmake
        GITHUB_REPOSITORY TheLartians/Ccache.cmake
        VERSION 1.2
    )
endif()

`launch-c` and `launch-cxx` must be in project directory.

Ccache.cmake/CMakeLists.txt

Lines 22 to 23 in e0171fb

	configure_file(launch-c.in launch-c)
	configure_file(launch-cxx.in launch-cxx)

In the current version, the launch-c and launch-cxx files need to be present in the project directory (the project which is using Ccache.cmake). A use case that disallows this is to clone this project (Ccache.cmake) and then just include its main CMakeLists.txt file in place from the project using it. For example, when compiling a project I might say:

$ cmake -DCMAKE_PROJECT_a_project_INCLUDE=/path/to/Ccache.cmake ..

This statement works if I include launch-c and launch-cxx in the project directory, but not otherwise, due to the bare references to them in the main CMakeLists.txt file.

I suggest adding ${CMAKE_CURRENT_LIST_DIR}/ prefix to them to allow the project to be included from anywhere.
