lib_deps piolibdeps issue creates dependences on all platforms

[txinto]

What kind of issue is this?

A library dependency and env platforms crossed issue. Piolibdeps directory is applying lib_deps in wrong compilation environments.

Description of problem

I have a project that has to be compiled on many platforms. The Arduino Uno is the last platform environment of my platformio.ini file, and it is the only one with the "Arduino Motor Shield" library dependence. With an empty .piolibdeps everything is compiling without problems, but when I try to launch another compilation, all the other platforms fail (Teensy, ESP32...). The reason is that the first compilation created a .piolibdeps/ArduinoMotorShieldLibrary_ID28 folder, and this folder is being compiled in all the platforms (not only on Uno). As a result, the second time you compile, it fails.

Steps to Reproduce

1. Use the given platformio.ini file in a project.
2. Compile it once --> ok.
3. Compile it twice --> error!
4. Delete the .piolibdeps/AdafruitMotorShield....ID27 folder.
5. Compile it again --> ok.
6. Compile it again --> error!.

Actual Results

Tries to compile wrong libraries in compilation environment that do not depend on them.

Expected Results

The compilation environment must only compile the libraries they depend on.

exact same issue here with PlatformIO, version 3.5.0a17

It seems that you have IFDEF guard for different dev/Platforms. Please take a look at chain+ of http://docs.platformio.org/en/latest/librarymanager/ldf.html#dependency-finder-mode

How do I handle this situation for libraries where I try to have a CI integration?
