OK, your right, it does prefer names that show up first in the name list
even if they are later in the total path.
Here is what the code does:
The ivar this->SearchPaths is the super path in the this function:
std::string cmFindProgramCommand::FindProgram(std::vector<std::string>
names)
{
std::string program = "";
if(this->SearchAppBundleFirst || this->SearchAppBundleOnly)
{
program = FindAppBundle(names);
}
// this is the main search, it passes in a list of names,
// and the super path
if(program.empty() && !this->SearchAppBundleOnly)
{
program = cmSystemTools::FindProgram(names, this->SearchPaths, true);
}
if(program.empty() && this->SearchAppBundleLast)
{
program = this->FindAppBundle(names);
}
return program;
}
// FindProgram loops over the names and trys to each
// name in the total path
//
kwsys_stl::string SystemTools::FindProgram(
const kwsys_stl::vector<kwsys_stl::string>& names,
const kwsys_stl::vector<kwsys_stl::string>& path,
bool noSystemPath)
{
for(kwsys_stl::vector<kwsys_stl::string>::const_iterator it =
names.begin();
it != names.end() ; ++it)
{
// Try to find the program.
kwsys_stl::string result = SystemTools::FindProgram(it->c_str(),
path,
noSystemPath);
if ( !result.empty() )
{
return result;
}
}
return "";
Not supper easy to fix... FindProgram is actually a pretty complicated
function. But, if someone wants to test/send a patch... :)
Might break something, but I doubt it. If you have two copies of
something on a machine, you are bound to make someone unhappy some of
the time by picking the wrong one...
