-export CMAKE_CXX_COMPILER_LAUNCHER=/usr/bin/ccache
-export CMAKE_C_COMPILER_LAUNCHER=/usr/bin/ccache
-```
-
-2.) Pass in cache variables
-
-```
-cmake ... -D CMAKE_CXX_COMPILER_LAUNCHER=/usr/bin/ccache -D CMAKE_C_COMPILER_LAUNCHER=/usr/bin/ccache
-```

-### EXPORT_COMPILE_COMMANDS
-
-There are 2 methods to enable exporting compile commands:

-
-```bash
-# Requires CMake 3.17 (https://cmake.org/cmake/help/latest/envvar/CMAKE_EXPORT_COMPILE_COMMANDS.html)
-export CMAKE_EXPORT_COMPILE_COMMANDS=ON
-```
-
-2.) Pass in cache variables
