Nice person, helpful for us. Abou cache they they explained well. Thank you very much. Create directory, first, which is empty and build folder. We could easily understand this tool well. * We've thought which is code-analyzer and create auto-configure well. * about audacity they created it by use of cmake. so, we could compiled it well and cmake is very useful for that creation, so that we could use makefiles already thank you very much.

We could yum-search cmake-gui, install it and boot it so that easily create project files for compilation, which means almost make files as configured: cmake-gui can use VERSION 3.6.1 if you add entry: message is the below: CMake Error: The source directory "...../read_005/src" does not appear to contain CMakeLists.txt. Specify --help for usage, or press the help button on the CMake GUI. We must create CMakeLists.txt but we can select "from UNIX makefile" as "Configure". "cmake-gui" itself is CMake 2.8.12.2 displayed. We could see CmakeCache.txt like the below so that we could not create tags by use of cmak-gui. ######################## # EXTERNAL cache entries ######################## cmake_minimum_required:STRING=VERSION 3.6.1 We'd rather love: cmake_minimum_required(VERSION 3.6.1) cmake-gui version itself must be higher, at least, we think.  (20200911: cmake3-gui) Configured and Generator: Now they are same. --- CMake Error: The source dir...
