See note in comment; concrete example of build error (when building
syncthingtray against qtforkawesome built with CMake 3.24.0):
```
CMake Error at plasmoid/lib/CMakeLists.txt:15 (find_package):
Found package configuration file:
/usr/share/qtquickforkawesome-git/cmake/qtquickforkawesome-gitConfig.cmake
but it set qtquickforkawesome-git_FOUND to FALSE so package
"qtquickforkawesome-git" is considered to be NOT FOUND. Reason given by
package:
The following imported targets are referenced, but are missing:
qtforkawesome-git
```
On 32-bit platforms `std::size_t` is just 4 bytes big which is not enough
to handle large data sizes. Using `std::streamsize` would likely be most
appropriate but switching signdness is likely not the best idea for
compatibility and it would mean a comparison with different signdness
because the buffer size is still `std::size_t`. So using `std::uint64_t`
now.
* Use auto
* Use `CPPUNIT_ASSERT_EQUAL` with `std::string_view` instead of `strcmp`
for better error messages in case of a failure
* Avoid instantiating an `std::string` in checks using `std::string_view`
instead
Fix
```
pragma diagnostic pop could not pop, no matching push
```
The GCC documentation says "If a pop has no matching push, the
command-line options are restored." but that's apparently not working here.
This might avoid
```

Building shared and static libraries at the same time has been removed as
of version 5 so this message would never be printed and it is not clear
anymore what the actual problem was.
This variable was never actually used. I suppose I've been adding it for
places where the config should be added as a prefix. However, this would be
inconsistent and now would also mean a confusing overlap with the
namespacing feature. So let's just remove it.
