when I do make intall-html and make install-pdf if the gprofng gui build tree, they do not get installed in the install directory
but in the source tree.

I have the following 3 directories: one for the source, one for the build, one for the install:

gprofng-gui  gprofng-gui-build  gprofng-gui-install

and this is what I see:

ezannoni@fedora:~/gprofng-gui-savannah$ find . -name *.pdf
./gprofng-gui/doc/gp-gui-ug.pdf
./gprofng-gui-build/doc/gp-gui-ug.pdf

ezannoni@fedora:~/gprofng-gui-savannah$ find . -name *.html
./gprofng-gui/doc/gp-gui-ug.html
./gprofng-gui/org/gprofng/mpmt/icons/allicons.html
./gprofng-gui-build/doc/gp-gui-ug.html


As you can see the pdf and html are installed in the source directory, doc subdirectory

Just to verify:

ezannoni@fedora:~/gprofng-gui-savannah/gprofng-gui$ git status
On branch master
Your branch is up to date with 'origin/master'.

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
    modified:   doc/version.texi

Untracked files:
  (use "git add <file>..." to include in what will be committed)
    doc/gp-gui-ug.html
    doc/gp-gui-ug.pdf
    doc/stamp-vti

no changes added to commit (use "git add" and/or "git commit -a")

it also modified the version.texi (but that might be normal, not sure)

thanks!
