Unable to compile Catch2 using meson

Now that Catch2 has its own Meson.build file for integration, I am filing this here too, this bug might lie with meson (see: [Here](https://github.com/mesonbuild/meson/issues/11304?ts=4) for a similar issue ) but i have only been able to reproduce it with Catch2.

**Describe the bug**
When attempting to compile a project using meson, consuming clang as a dependency via the subproject or wrapper functionality of meson, it gives the following compiler error:
Somehow, the paths for Catch2's libraries seem to contain mixed slashes and do not get resolved correctly.

**Expected behaviour**
Catch2 has the correct paths and compiles like expected.

**Reproduction steps**
catch2.wrap:
```
[wrap-git]
url = https://github.com/catchorg/Catch2.git
revision = devel
depth = 1

[provide]
catch2 = catch2_dep
catch2-with-main = catch2_with_main_dep
```

Meson.build:
```
project('testcatch2', 'cpp')
catch2_dep = dependency('catch2-with-main', version: '>=3')
```

repro.bat:
```
set CXX=clang++
meson setup build
meson compile -C build
```
