[Bug] Incorrect macro expansion during compile task in 1.23.24

Nobody has claimed this yet.

### Brief Issue Summary

Hi everyone.
I would like to thank all of yours for your outstanding work.
It seems that in latest version during compile task some kind of incorrect macro expansion was occured.
For example, 1.23.5 expand command line for google log as follows :
/usr/bin/g++ -DBOOST_PROGRAM_OPTIONS_DYN_LINK -DBOOST_PROGRAM_OPTIONS_NO_LIB -DFMT_LOCALE -DFMT_SHARED -DGFLAGS_IS_A_DLL=0 -DGOOGLE_GLOG_DLL_DECL="" -DGOOGLE_GLOG_DLL_DECL_FOR_UNITTESTS="" .........
Latest version (1.23.24) produces the followed[after rm -rf ./build, restart ide, clean/configure/build]:
/usr/bin/g++ -DBOOST_PROGRAM_OPTIONS_DYN_LINK -DBOOST_PROGRAM_OPTIONS_NO_LIB -DFMT_LOCALE -DFMT_SHARED -DGFLAGS_IS_A_DLL=0 "-DGOOGLE_GLOG_DLL_DECL=\"\"" "-DGOOGLE_GLOG_DLL_DECL_FOR_UNITTESTS=\"\"" ..........
Please note erroneous extra quotes before -DGOOGLE... .
Version at least 1.23.22 is free from this.
Build the whole source tree is successfull,however.

```shell
There are a lot of internal file system entries which are not relevant but cannot be exposed.
```

### Additional Information

_No response_

Start by reproducing the compile task with the command-line definitions shown in the issue, comparing versions 1.23.22 or 1.23.5 with 1.23.24. Trace the macro-expansion path that generates the g++ arguments; done means the GOOGLE_GLOG definitions are emitted without the extra surrounding quotes. The issue does not name a file, test, or reproducible project.
