  (it already worked for me, but at least this patch doesn't break things)

  However, your patch still misses the following things:

- The commit message is too vague.  It should describe the problem in more detail,
including the root cause.  For example:

grantlee: fix -lpthread build error

Build fails because of missing -lpthread with toolchains that need it. It
gives an error log like:
Linking CXX executable testgenerictypes_exec

- The patch itself should contain an equally detailed description (can be a copy
of the commit message).  It should also have your Signed-off-by line.


  Both of these are minor things, however.

  Arnout
