Header-only Library how to include

See original GitHub issue

I want to use a header only github project, so I created my with this in it:

from conans import ConanFile, tools

class SimpleSignalConan(ConanFile):
    name = "SimpleSignal"
    version = "master"

    def source(self):
        git = tools.Git(
        git.clone('', branch=self.version)

In my CMakeLists.txt, I did the following:

if(CONAN_EXPORTED) # in conan local cache
    # standard conan installation, deps will be defined in
    # and not necessary to call conan again, conan is already running
else() # in user space
    # Make sure to use to define dependencies, to stay consistent

In my main.cpp, I tried doing #include <SimpleSignal.h>, but it didn’t work.

What else do I need in order to be able to #include <SimpleSignal.h>?

Hi @smac89, Yes, you can use the variable CONAN_EXPORTED to check if you are running on Conan’s local cache or in user space. That way you can test your project using cmake-conan but also creating the package using Conan commands directly. I thought that for your case it was easier to explain it without making both things as you are just consuming the SimpleSignal package. I have created a complete example on how to use cmake-conan for both consuming and creating packages that maybe clears a little the explanation in the docs.
