hunter_config(... URL ... SHA1 ...) fails with transitive dependencies

• I've read Brief overview section and do understand basic concepts. Yes
• I've read F.A.Q. section and there is no solution to my problem there. Yes
• I've read Code of Conduct, I promise to be polite and will do my best at being constructive. Yes
• I've read Reporting bugs section carefully. Yes
• I've checked that all the hunter_add_package/find_package API used by me in the example is the same as in documentation. Yes
• I'm using latest Hunter URL/SHA1. Yes

• I've created SSCCE reproducing the issue:

Here is the log until first error reported by Hunter, option `HUNTER_STATUS_DEBUG` is `ON`:
* [out.txt](https://github.com/cpp-pm/hunter/files/3675146/out.txt)

I've checked that the first error in logs **IS NOT** `external.build.failed`. **Yes**

<!--- Info about environment -->
* I'm building on Linux
* I'm using system CMake
* CMake version: 3.10.2

* I'm not using toolchain

I'm using the next command line on generate step:

cmake -H. -Bbin

In this testcase I'm including the package lehrfempp. The lehrfempp package in turn depends again on Boost::program_options . If I omit the `hunter_config` directive, everything works as expected but I don't get the version that I want. If I use the `hunter_config`  directive, hunter seems to download the correct version of lehrfempp but then later on the find_package call fails.

So when you don’t specify the config, it is using the default version of lehrfempp that has already been added to hunter. When you do specify the config, you are choosing a specific version (I believe 0.8) that hasn’t been added to hunter or tested in hunter. Has anything changed in that package between versions that may cause this?

[craffael]

You were right. I should have tested this more thoroughly, there was one commit that introduced an error in the meantime. Arrgh.
