I have the following code code specify various output dir and the dest dir

Qt Code: 
  1. BUILD_ROOT = $${PWD}/build/$$TARGET-$$TEMPLATE
  2. DIST_ROOT = $${PWD}/dist
  3.  
  4. CONFIG(debug, debug|release) {
  5.     BUILD_ROOT = $${BUILD_ROOT}/debug
  6.     DIST_ROOT = $${DIST_ROOT}/debug
  7. } else {
  8.     BUILD_ROOT = $${BUILD_ROOT}/release
  9.     DIST_ROOT = $${DIST_ROOT}/release
  10. }
  11.  
  12. DESTDIR = $${DIST_ROOT}
  13. OBJECTS_DIR = $${BUILD_ROOT}/obj
  14. MOC_DIR = $${BUILD_ROOT}/moc
  15. RCC_DIR = $${BUILD_ROOT}/rcc
  16. UI_DIR = $${BUILD_ROOT}/ui
To copy to clipboard, switch view to plain text mode 

However when the PWD is expanded to a path that contains spaces, the final makefile will fail when build.

This is the compile output:
Qt Code: 
  1. Running build steps for project logging...
  2. Configuration unchanged, skipping qmake step.
  3. Starting: "C:\QtSDK\mingw\bin\mingw32-make.exe"

Notice the line:
g++ -Wl,-s -mthreads -shared -Wl,--out-implib,c:\Documents and Settings\Grayfox\Desktop\root\projects\logging\tru nk\dist\release\liblogging.a -o

The path is not quoted, which cause this error:
g++: Settings\Grayfox\Desktop\root\projects\logging\tru nk\dist\release\liblogging.a: No such file or directory

Normally, if I do not explicitly set a DESTDIR, the path above would have quotes around them.

Is this a known issue?
