Configuring incomplete, errors occurred!
A guy told me that I should add something like this:
In Header Files\\ogr\ogrsf_frmts need to add terminator '\' like this:
"Header Files\\ogr\\ogrsf_frmts"
but as I paste the common.cmake file content line 5:
source_group("Header Files\\${FGROUP}" FILES ${GDAL_AHHEADERS})
the string after Header Files is replaced by FGROUP macro, may generated automatically by CMake, so I can not edit them.
The error is happening because the contents of the variable ${FGROUP} contain paths with Windows-style separators. These are treated by CMake as escape characters.
You should change your macro to a function to avoid this. From the docs for macro:
Note that the parameters to a macro and values such as ARGN are not variables in the usual CMake sense. They are string replacements much like the c preprocessor would do with a macro. If you want true CMake variables you should look at the function command.

I've installed OpenSSL, but I don't know why CMake won't let me run the code.
This issue is a bug introduced in CMake version 3.17.3, see the commit here. The code change was intended to update the how CMake parses the OpenSSL version number, but the regex used by the CMake maintainers was malformed.
The issue was quickly patched in CMake 3.18.0-rc1 here, so if you upgrade to the latest CMake version the issue will be resolved.
I want to use the --warn-unused-vars flag with CMake, but it floods the output with warnings to unused CMAKE_* variables. It happens even with an empty CMakeLists.txt file, but to generate an example I used this one:

project(p)
set(myVar)
If I run cmake --warn-unused-vars .. it generates the following output:

[This and similar stuff goes on for 6000+ lines]
I expected CMake to only warn about myVar (it does warn about it as well among all that noise). Do I have to filter the output by myself or is there some kind of additional flag I have to pass or configuration I have to change in order to limit the warnings to my CMake files? With -Wno-dev it also suppresses the warning about myVar which I want to keep.
I would like to download LightGbm and i followed this website for doing it. But suddenly stopped with an error. Please post a solution.
