I gave your example a try and I like how it is structured as well as how clear and concise the CMake is, but I ran into a problem. I ran install and successfully "installed" the Foo project.

When I try to use Foo::bar and Foo::baz in another project, the find_package fails because the check_components function fails when it's searching for the required components. Any ideas how to fix this so that the components are successfully found? If that check isn't there everything works fine.

@mrostecki added this pull request to my project. I asked him to please post it here but I don't think he has had time to do so. I was wondering how you feel about this issue. Below is a quote from the linked PR.

The common practice in cmake to allow to specify the libdir is using the LIB_INSTALL_DIR variable. The main use case of that variable is setting /usr/lib64 as the destination dir for libraries which is a common pattern in many Linux distributions.

I would like to setup third parties project like proposed in this example.

However, I would like that the setup of these third parties package are done by my main project cmake.

If the third party package is not there, then install it .... (most of them are git repository based)

have you got an idea on how to proceed ?

The examples are missing the include folder for the installed library

Thank you for this example. There is something that does not seem satisfying: the monolithic build works only if the order of commands add_subdirectory in the top-level CMakeLists.txt is correct. Is there not a way to improve on this? (Imagine a set of a dozen libraries with various dependencies between them.)
