Error when waf binary from PATH.

[knowack1]

Hi,

thank You for a very nice plugin.
In our environment we have waf binary installed in the system.
Hence my configuration is:
set makeprg=waf

Unfortunately this leads to an error:
"binary specified in 'makeprg' not found"

Currently I locally patch plugin sources to solve this problem:

--- a/plugin/buildmenu.vim
+++ b/plugin/buildmenu.vim
@@ -262,7 +262,7 @@ function! s:buildMenu.RunPreChecks() dict
                echoe "g:BuildmenuPosition contains illegal value! set it to 'left' or to 'right'"
        endif
 
-       if !filereadable(&makeprg)
+       if !executable(&makeprg)
                echoe = "error: binary specified in 'makeprg' not found (" . &makeprg . ")." . s:abortmsg
        endif

Maybe It is worth to consider above in master branch.

Thanks,
Karol
