[bug]Error In conanbuildenv LD_LIBRARY_PATH

[crystalsky]

Describe the bug

StepA

proja

class conan_proja(ConanFile):
    name="proja"
    version="0.1"
    def requirements(self):
        self.requires("glog/0.3.5")
  
    def config_options(self):
        self.options["glog"].shared=True

There is A Libaray and A Excutable in ProjeA. The Libaray and Excutable use The Glog Libaray.
conan create .
Will Done When Create the Proja and c++ projects.

projb

class conan_projb(ConanFile):
    name="projb"
    version="0.1"
    def requirements(self):
        self.requires("proja/0.1")

And Use Create.
conan create . --build

Error: /usr/bin/lib: warning: libglfags_nothreads.so.2.2 , needed by /usr/lib/libglog.so.0, not found (try using -rpath or -rpath-link) //root/.coan2/p/glog46e0c3677c070/p/lib/libglog.so.0.3.5: gflags::FlagRegisterer::FlagRegisterer.... undifined symbol

Step2

1. Add The Code To Gflags ConanFile Like This:

class GflagsConan(ConanFile):
    name = "gflags"
    version = "2.2.2"
    def package_info(self):
        ...
        ...
        if self.settings.os=="Linux" and self.settings.shared:
            self.buildenv_info.append("LD_LIBRARY_PATH", self.package_folder+"/lib")
        if self.settings.os=="Windows" and self.settings.shared:
            self.buildenv_info.append("PATH", self.package_folder+"/bin")
            self.buildenv_info.append("PATH", self.package_folder+"/lib")

2. Recreate The Project
   sh cd projeb && conan create . --build ‍

3. This Result the Project B Not Build Success. Found The Error Like This. No ':' in export LD_LIBRARY_PATH=xxx
   conanbuildenv-release-x86_64.sh
   ‍ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH /root/.conan2/p/gflags46e0c3677c070/p/lib ‍

May Be Is A Bug or I use it with a mistake.

Hi @crystalsky

Make sure all the relevant recipes have a package_type that reflect what they are.

Most likely proja is missing a package_type:

• shared-library if it is always a shared library
• library with shared option if its configurable
