after find_package is invoked, several variables will be set. You use these to augment your compiler and linker information, e.g.:
target_include_directories(mytarget $ZLIB_INCLUDE_DIRS) target_link_libraries(mytarget $ZLIB_LIBRARIES) …and so on for other modules you find (OpenSSL, for example). You can also choose to add the include paths “globally” using include_directories(), but it’s usually considered best practice to modify individual target properties where possible. -Mike .. > On Apr 21, 2017, at 10:58 AM, Alex Chen <alex_c...@filemaker.com> wrote: > > Although cmake uses the path I supplied for OpenSSL and Zlib, I do not see > the –I flag being used in compiling the code.
