Hello, How should I properly setup a header-only library in cmake such that: 1. The headers appear in the Visual Studio solution. 2. In an executable i can use target_link_libraries(<TARGET> <HEADER_ONLY_LIBRARY>) to specify that I want to use (the headers of) this library.
So far I have considered two options: a) create a INTERFACE library using add_library(<HEADER_ONLY_LIBRARY> INTERFACE), this fulfills property 2. from above but not 1. b) create a usual library and set LINKER_LANGUAGE to CXX. In this way 1. works but 2. doesn't work unfortunately because the executable will try to link to a library that does not exist. Notes: - A not so nice workaround is to go with b) and add an empty source file to it. - Another option would be to not link the executable with the HEADER_ONLY_LIBRARY. However one thing that I like about target_link_libraries is that all the "usage requirements" from the HEADER_ONLY_LIBRARY (such as include directories and compile options) are applied to the executable automatic. So if I don't use target_link_libraries I would have to set these options manually (unless there is another alternative?). I would be very happy for some suggestions :) Raffael P.S.: See also the (a bit outdated) discussion http://stackoverflow.com/a/11583676/2796908.http://stackoverflow.com/a/11583676/2796908.
