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
