quotes in --sysroot breaks clangd

[Logiase]

Describe the bug
set --sysroot in utilities.cmake breaks clangd.

Sources to reproduce
any exmaple.

Steps to reproduce

1. Copy and build an example
2. take a look at compile_commands.json, and you will see --sysroot=\\\"/usr/arm-none-eabi\\\"
3. run clangd --check={any source}, and there's an error means clangd cant find system headers, and check interlnal (cc1) args in output, the redundant quotes and slash breaks the path.

Expected behavior
clangd is a very common lsp server, it should works fine

Screenshots

quotes break paths in clangd:

see -isysroot "\"/usr/arm-none-eabi\"" and -internal-isystem "\"/usr/arm-nonea-eabi\"/include"

redundant quotes and slashs in compile_commands.json:

Environment (please complete the following information):

• OS: ArchLinux

• Compiler: arm-none-eabi-gcc 12.2.0

• stm32-cmake: abea019 (newest)

• cmake: 3.25.1

• HAL/cube/CMSIS: stm32cubeh7 v1.11.0

Additional context
This problem has no effected on compilation, but it cause most IDE or editors which use clangd as LSP server does not work.

For example, math.h not found.

Remove quotes in utilities.cmake can solve this problem, but it also affects spaces in sysroot path.

while the stm32cube hal library has no space protection

I think it should be mentioned somewhere and tell users how to make clangd work, or just remove the quotes.

Hello,

Thanks for this detailed issue. I can confirm this is an issue right now, but the solution is actually already on PR #290.
I will try to merge this PR and solve your issue :)

Hi

PR #290 can fix this issue, and correctly handles the spaces in sysroot path without redundant slash.

with spaces:

without spaces:

closing as fixed in #290
