Better CMake use of find_clang.cr #51

Open docelic opened 4 years ago

docelic commented 4 years ago

Currently, CMake calls find_clang.cr 3 times and also parses its stdout. This causes the cmake run time to be longer than needed, and also it makes find_clang.cr unable to print meaningful debug/info messages because its output is parsed directly.

We can improve this in the following way:

1) Make CMake call find_clang.cr only once 2) Make find_clang.cr generate all of its content at once and dump it into various files on disk. (Currently it already generates 3 files, but it could generate at least 2 more - one with one for output of --print-clang-libs and one for output of --print-llvm-libs) 3) CMake should then read in those file 4) find_clang.cr will then be able to print info/notices to stdout, such as the value of its autodiscovery of BINDGEN_DYNAMIC setting as well as the paths/filenames of all the files it has generated
