The CMake build of google-cloud-cpp fails with this error:

CMake Error at google/cloud/storage/CMakeLists.txt:17 (find_package):
  Could not find a package configuration file provided by
  "google_cloud_cpp_common" with any of the following names:

    google_cloud_cpp_commonConfig.cmake
    google_cloud_cpp_common-config.cmake

  Add the installation prefix of "google_cloud_cpp_common" to
  CMAKE_PREFIX_PATH or set "google_cloud_cpp_common_DIR" to a directory
  containing one of the above files.  If "google_cloud_cpp_common" provides a
  separate development package or SDK, be sure it has been installed.

Is this the [repo](https://github.com/googleapis/google-cloud-cpp) you are trying to compile? — Kevin, Mar 20 '20 at 15:45
@squareskittles https://github.com/googleapis/google-cloud-cpp yes — mortymacs, Mar 20 '20 at 15:48
Ok, that repo has specific instructions for building on different environments (Mac, Linux, etc), did you follow those instructions? Specifically, `cmake -Hsuper -Bcmake-out`. Note, the *source* directory should be `super`, did you run your command from the `super` directory? — Kevin, Mar 20 '20 at 15:53
In the `INSTALL.md` file they mentioned something else: https://github.com/googleapis/google-cloud-cpp/blob/master/INSTALL.md#installing-google-cloud-cpp — mortymacs, Mar 20 '20 at 15:57
Yes, but the note in the `INSTALL.md` file says those commands **only** apply "*If all the dependencies of google-cloud-cpp are installed and provide CMake support files*". It appears you have *not* installed all of the dependencies. However, the same file has instructions for installing *specific* missing dependencies for each environment (Linux, Mac, etc.), so you probably need to *install* the missing `google_cloud_cpp_common`. — Kevin, Mar 20 '20 at 16:00
Glad it works! Added a response to more clearly explain things. — Kevin, Mar 20 '20 at 16:16

The CMake command:

cmake -H. -Bcmake-out

will only work well after you have installed all of the google-cloud-cpp dependencies. From the INSTALL.md file:

If all the dependencies of google-cloud-cpp are installed and provide CMake support files, then compiling and installing the libraries requires two commands:
cmake -H. -Bcmake-out
cmake --build cmake-out --target install
Unfortunately getting your system to this state may require multiple steps, the following sections describe how to install google-cloud-cpp on several platforms.

It goes on to describe how to install each of the dependencies individually, for several platforms. This is a painful process, but an easier approach is use the suggested CMake super-build, described in the main README.md file. This will download and build all of the google-cloud-cpp dependencies for you. Try the CMake super-build command instead:

cmake -Hsuper -Bcmake-out
