Hi, I have installed boost by conda and it install correctly. The following packages will be downloaded: package | build ---------------------------|----------------- boost-1.78.0 | py310h220cb41_4 555 KB conda-forge ------------------------------------------------------------ Total: 555 KB The following NEW packages will be INSTALLED: boost conda-forge/win-64::boost-1.78.0-py310h220cb41_4 But CMake gives configuration errors : CMake Error at C:/Users/Raivo/miniconda3/Library/lib/cmake/Boost-1.78.0/BoostConfig.cmake:141 (find_package): Found package configuration file: C:/Users/Raivo/miniconda3/Library/lib/cmake/boost_filesystem-1.78.0/boost_filesystem-config.cmake but it set boost_filesystem_FOUND to FALSE so package "boost_filesystem" is considered to be NOT FOUND. Reason given by package: No suitable build variant has been found. The following variants have been tried and rejected: * boost_filesystem.lib (shared, Boost_USE_STATIC_LIBS=ON) Still Boost is useless for me as I wanted to build Point CLoud Lib, bud CMake stops on these errors. What I have to do ? And how to go forward ? Can anybody help me ? Regards Raivo
