[SOLVED] Have troubles with the CMake build directory

Issue

I have a very simple CMakeLists.txt file:

cmake_minimum_required(VERSION 3.15)
project(Test_documentation)

find_package(Doxygen)
if (Doxygen_FOUND)
    find_file(DOXYGEN_PLANTUML_JAR_PATH
        plantuml.jar
        $ENV{PLANT_UML_JAR_PATH}
        /usr/share/plantuml
    )

endif (Doxygen_FOUND)

(I did have more but I stripped it down whilst trying to fix this issue).

I want to run a simple out-of-source build (on Windows - though I know one of those plantuml search path's is Linux-related).

PS D:\cmaketest> cmake D:\repos\My\far\away\project\Doc\CMakeLists.txt
....
-- Build files have been written to: D:/repos/My/far/away/project/Doc

Nothing gets written in cmaketest at all (and I want the build files to be written there and .\Doc to be unchanged.)

There are no other CMake-related files in ...\Doc.

What have I got wrong here as I want an out of source build and not for any of the build files to be in the source directory.

Solution

I solved this by using the -S (path to source) and -B (path to build) options.

ie.

 cmake -S D:\repos\path\to\my\far\away\project\Doc -B .

Will find the CMakeLists.txt in the Doc directory and build a tree in the current directory.
