find_dependency() does not support COMPONENTS argument before 3.8.0

[CDitzel]

after building the lib, I wanted to compile the example, but upon putting cmake .. in a build directory, I got

`CMake Error at /usr/share/cmake-3.5/Modules/CMakeFindDependencyMacro.cmake:45 (message):
Invalid arguments to find_dependency
Call Stack (most recent call first):
/usr/local/lib/cmake/JSONUtils/JSONUtilsConfig.cmake:5 (find_dependency)
CMakeLists.txt:6 (find_package)

-- Configuring incomplete, errors occurred!
See also "/home/me/tempRepos/modern-cmake-sample/example_exec/build/CMakeFiles/CMakeOutput.log".
`

what seems to be the problem here?

Which CMake version are you using? What does /home/me/tempRepos/modern-cmake-sample/example_exec/build/CMakeFiles/CMakeOutput.log say?

Alright I had to dig a little bit but think I found your issue. The problem is that in your CMake version (v3.5.0), the COMPONENTS argument is not supported by find_dependency(). See the implementation.

    find_package(${dep} ${cmake_fd_version}
        ${cmake_fd_exact_arg}
        ${cmake_fd_quiet_arg}
        ${cmake_fd_required_arg}
    )

Thus the error comes from the line find_dependency(Boost 1.55 REQUIRED COMPONENTS regex) as this is not recognized. Apparently this was only introduced after v1.8.0. I will remove this and use find_package() directly instead. Sorry about this.

@CDitzel I commited f6e026e the changes and it should work now with your CMake version.

I greatly appreciate it, whats the differencebetween find_package and find_dependency anyway

[pabloariasal]

They are practically the same, find_dependency() is just a wrapper around find_package() that produces better error messages as it knows it's being run by downstreams inside a .config

Hello, I have the same problem with you. How did you solve it?The latest version of my cmake is 3.5.1. Which version is 3.8.0?

I just happened upon this with the same problem @yaolinggezhu . Literally just replace find_dependency with find_package that's all you need.
