I jumped on this quick! :-) And ran into a problem. This happens when running cmake. The solution was to install catch2-devel using DNF. Note that there is also a package called "catch22-devel" which I did not install. After installing catch2-devel, the compile and install proceeded with no problems. =============== -- Checking for module 'proj' -- Found proj, version 9.2.1 CMake Error at cmake/Catch2.cmake:17 (find_package): By not providing "FindCatch2.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "Catch2", but CMake did not find one. Could not find a package configuration file provided by "Catch2" with any of the following names: Catch2Config.cmake catch2-config.cmake Add the installation prefix of "Catch2" to CMAKE_PREFIX_PATH or set "Catch2_DIR" to a directory containing one of the above files. If "Catch2" provides a separate development package or SDK, be sure it has been installed.
