#include __LV_TO_STR(LV_CONF_PATH) fails if LV_CONF_PATH contains spaces

PlatformIO running through JetBrains CLion on Windows

What happened?

I have a PlatformIO project set up for a project I'm working on. I have my lv_conf.h inside the PlatformIO include folder and used this line in the platformio.ini file to tell LVGL where to find it:
build_flags = -D LV_CONF_PATH="$PROJECT_INCLUDE_DIR/lv_conf.h"

When I tried to build the project, I encountered this error:

In file included from .pio/libdeps/lolin_c3_mini/lvgl/src/lv_init.h:16,
Compiling .pio\build\lolin_c3_mini\src\main.cpp.o
                 from .pio/libdeps/lolin_c3_mini/lvgl/LVGL.h:21,
                 from src/Display/Display.h:8,
                 from src/Display/Display.cpp:5:
.pio/libdeps/lolin_c3_mini/lvgl/src/lv_conf_internal.h:54:42: fatal error: D://College_project/include/lv_conf.h 1/Repoless: No such file or directory
         #include __LV_TO_STR(LV_CONF_PATH)

I then tried commenting out the include line mentioned in the error and replaced it with this explicitly defining the file's path:

#include "D:/Projects/Repoless Projects/College_project/include/lv_conf.h"

This let the project compile successfully.

After undoing that change, I then tried renaming the Repoless Projects folder to replace the space with an underscore. This also let my project compile successfully.

How to reproduce?
