c++ - Coapp / autopkg : multiple include folders in /build/native/include/ -

i trying build nuget package via coapp tool c++. package needs embed 3 folders when compiling cpp using it.

so, want internal include structure following :

/build/native/include/lib1, /build/native/include/lib2, /build/native/include/lib3

my question: how add several include folders in /build/native/include/

i tryied :

multiple blocs of (varying lib1, lib2, lib3):

    nestedinclude +=      {          #destination = ${d_include}lib1;          ".\lib1\**\*.hpp", ".\lib1\**\*.h"     }; 

multiple blocs of (varying lib1, lib2, lib3):

    nestedinclude      {          #destination = ${d_include}lib1;          ".\lib1\**\*.hpp", ".\lib1\**\*.h"     }; 

but seems coapp accumulates .h/.hpp files among blocs (depending of operator += or not) , @ end, add of them last #destination tag value. unique entry : /build/native/include/lib3

the destination overwritten in example , therefore flat in last given address. handle can instead create multiple nested include,

   nested1include: {          #destination = ${d_include}lib1;          ".\lib1\**\*.hpp", ".\lib1\**\*.h"    }     nested2include: {              #destination = ${d_include}lib2;              ".\lib2\**\*.hpp", ".\lib2\**\*.h"    }
