SUMMARY
I use ccls as language server, and it will make KDEClangFormat unhappy when I
run cmake.
STEPS TO REPRODUCE
0. Have clang-format executable
1. Have ccls run as your language server in the kwin repo
2. cmake in the kwin repo
3.
OBSERVED RESULT
CMake Error at /home/user/kde/usr/share/ECM/kde-modules/KDEClangFormat.cmake:97
(add_custom_target):
The target name
"clang-format-.ccls-cache_@@home@user@kde@src@kwin_@usr@include@gentoo@fortify.h"
is reserved or not valid for certain CMake features, such as generator
expressions, and may result in undefined behavior.
Call Stack (most recent call first):
CMakeLists.txt:517 (kde_clang_format)
CMake Error at
/home/user/kde/usr/share/ECM/kde-modules/KDEClangFormat.cmake:100
(add_custom_command):
No TARGET
'clang-format-.ccls-cache_@@home@user@kde@src@kwin_@usr@include@gentoo@fortify.h'
has been created in this directory.
Call Stack (most recent call first):
CMakeLists.txt:517 (kde_clang_format)
(and more errors like this)
EXPECTED RESULT
No errors should occur.

ADDITIONAL INFORMATION
The KDEClangFormat.cmake says the following:
```
To exclude directories from the formatting add a ``.clang-format``
file in the directory with the following contents:
.. code-block:: yaml
DisableFormat: true
SortIncludes: false
```
But after I added .clang-format file with the specified content inside
.ccls-cache and it still show up the errors in cmake.
contents in the .ccls-cache directory:
```
