With that combination the first search seems to happen in CONFIG mode but subsequent searches will use MODULE mode. This will result in the following warning: CMake Warning at /usr/share/cmake-3.18/Modules/FindBoost.cmake:1187 (message): New Boost version may have incorrect or missing dependencies and imported targets Call Stack (most recent call first): /usr/share/cmake-3.18/Modules/FindBoost.cmake:1311 (_Boost_COMPONENT_DEPENDENCIES) /usr/share/cmake-3.18/Modules/FindBoost.cmake:1919 (_Boost_MISSING_DEPENDENCIES) cmake/Modules/OpmFind.cmake:135 (find_package) cmake/Modules/OpmFind.cmake:230 (find_and_append_package_to) cmake/Modules/OpmLibMain.cmake:83 (find_and_append_package_list_to) CMakeLists.txt:222 (include) Also the variable Boost_LIBRARIES will look quite messed up by occurrences of optimized and debug: Boost_LIBRARIES=optimized;/usr/lib/x86_64-linux-gnu/libboost_system.so.1.74.0;debug;/usr/lib/x86_64-linux-gnu/libboost_system.so;optimized;/usr/lib/x86_64-linux-gnu/libboost_unit_test_framework.so.1.74.0;debug;/usr/lib/x86_64-linux-gnu/libboost_unit_test_framework.so Which will make the modules unusable because of CMake errors during linking: CMake Error at /usr/share/dune/cmake/modules/DuneMacros.cmake:991 (target_link_libraries): The "debug" argument must be followed by a library. Call Stack (most recent call first): src/CMakeLists.txt:2 (target_link_dune_default_libraries) -- Configuring incomplete, errors occurred! Note this fix is only needed for Boost versions 1.70 and higher. Older versions do not provide cmake package configuration files (BoostConfig.cmake) and hence there can be no mixup. Note also that the alternative approach of setting CMAKE_FIND_PACKAGE_PREFER_CONFIG does not work for OPM as with this e.g. the Dune module versions would not be set correctly.
