CMake Error at CMakeLists.txt:63 (include):

CMake Warning at CMakeLists.txt:69 (find_package):
By not providing “FindLibStdCpp.cmake” in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
“LibStdCpp”, but CMake did not find one.

Could not find a package configuration file provided by “LibStdCpp” with
any of the following names:

LibStdCppConfig.cmake
libstdcpp-config.cmake

Add the installation prefix of “LibStdCpp” to CMAKE_PREFIX_PATH or set
“LibStdCpp_DIR” to a directory containing one of the above files. If
“LibStdCpp” provides a separate development package or SDK, be sure it has
been installed.
