Subject: [PATCH v5 01/18] configure, meson: override C compiler for cmake
Date: Wed, 19 Jan 2022 16:41:50 -0500	[thread overview]
Message-ID: <139b14d9db775e4fc8755f9974c0b5d593a14d3b.1642626515.git.jag.raman@oracle.com> (raw)
In-Reply-To: <cover.1642626515.git.jag.raman@oracle.com>

The compiler path that cmake gets from meson is corrupted. It results in
the following error:
| -- The C compiler identification is unknown
| CMake Error at CMakeLists.txt:35 (project):
| The CMAKE_C_COMPILER:
| /opt/rh/devtoolset-9/root/bin/cc;-m64;-mcx16
| is not a full path to an existing compiler tool.

Explicitly specify the C compiler for cmake to avoid this error
