[CMake] find_package and lib/cmake/Foo

[Biddiscombe, John A.]

Just to follow up my own question. I have found the answer
export Foo_DIR=/my/path/prefix
followed by cmake ... will correctly locate the package

unfortunately,
cmake -DFoo_DIR=/my/path/prefix <rest of options>
will not.

Is there a reason why the cmake variable is not searched, whereas the env var is?

thanks

JB

Subject: [CMake] find_package and lib/cmake/Foo

I've asked this before, but never resolved it...

if I stall package Foo into
CMAKE_INSTALL_PREFIX=/my/path/prefix
and generate
/my/path/prefix/lib/cmake/Foo/FooConfig.cmake
etc

then with
Foo_DIR=/my/path/prefix
Foo_ROOT=/my/path/prefix
find_package(Foo)
does not find package Foo

One needs to set
Foo_DIR=/my/path/prefix/lib/cmake/Foo
or
Foo_ROOT=/my/path/prefix/lib/cmake/Foo

but it specifically states in the documentation http://www.cmake.org/cmake/help/v3.2/manual/cmake-packages.7.html "One place it looks is: <prefix>/lib/cmake/Foo*/ where Foo* is a case-insensitive globbing expression"

if I
set(CMAKE_FIND_DEBUG_MODE 1)
then I do not see it searching in my prefix with any extra /lib/cmake/ paths.

Is the documentation wrong, or have I missed something?

thanks

JB
