Well, that's one way, but that doesn't really provide any benefit above the original solution (i.e. just define the JPEG_INCLUDES and JPEG_LIBRARIES variables accordingly). > it seems that I either > > - have to make a copy of FindJPEG.cmake, customize it to define > target JPEG::JEPG and ship it along with my project, Either that or you define it yourself: find_package(JPEG) if (JPEG_FOUND) add_library(JPEG::JPEG UNKNOWN IMPORTED) set_property( TARGET JPEG::JPEG PROPERTY IMPORTED_LOCATION ${JPEG_LIBRARIES} ) set_property( TARGET JPEG::JPEG PROPERTY INTERFACE_INCLUDE_DIRECTORIES ${JPEG_INCLUDES} ) endif() I admit it's not a huge benefit over just using the variables. The advantages: - you get slightly better error handling - your target_link_libraries commands are slightly more readable. > - or write my `../ExtLibs/libjpeg/CMakeLists.txt` so that it globally > defines JPEG_LIBRARIES and JPEG_INCLUDE_DIRS That will work, too.
