Yocto recipe python whl package

Question

I am writing a custom yocto recipe that should install a python package from a .whl file.

I tried it using a recipe that contains:

<

.whl package is just a .zip file with python sources, and precompiled binaries for certain platform.

So, you can do something like this:

COMPATIBLE_HOST = "i686.*-mingw.*"                                                                  

SRC_URI = "https://files.pythonhosted.org/packages/d8/9d/7a8cad803ef73f47134ae5c3804e20b54149ce62a7d1337204f3cf2d1fa1/MarkupSafe-1.1.1-cp35-cp35m-win32.whl;downloadfilename=MarkupSafe-1.1.1-cp35-cp35m-win32.zip;subdir=${BP}"

SRC_URI[md5sum] = "a948c70a1241389d7120db90d69079ca"                                                
SRC_URI[sha256sum] = "6dd73240d2af64df90aa7c4e7481e23825ea70af4b4922f8ede5b9e35f78a3b1"             

inherit nativesdk python3-dir                                                                       

LICENSE = "BSD-3-Clause"                                                                            

PV = "1.1.1"                                                                                        
PN = "nativesdk-python3-markupsafe"                                                                 

LIC_FILES_CHKSUM = "file:///${S}/MarkupSafe-1.1.1.dist-info/LICENSE.rst;md5=ffeffa59c90c9c4a033c7574f8f3fb75"

do_unpack[depends] += "unzip-native:do_populate_sysroot"                                            

PROVIDES += "nativesdk-python3-markupsafe"                                                          
DEPENDS += "nativesdk-python3"                                                                      

FILES_${PN} += "\                                                                                   
    ${libdir}/${PYTHON_DIR}/site-packages/* \                                                       
"                                                                                                   

do_install() {                                                                                      
    install -d ${D}${libdir}/${PYTHON_DIR}/site-packages/MarkupSafe-1.1.1.dist-info                 
    install -d ${D}${libdir}/${PYTHON_DIR}/site-packages/markupsafe                                 

    install -m 644 ${S}/markupsafe/* ${D}${libdir}/${PYTHON_DIR}/site-packages/markupsafe/          
    install -m 644 ${S}/MarkupSafe-1.1.1.dist-info/* ${D}${libdir}/${PYTHON_DIR}/site-packages/MarkupSafe-1.1.1.dist-info/
}

I haven't tested it, yet, but it already forms proper nativesdk package. Note downloadfilename= parameter to the SRC_URI - without it, .whl file would not be extracted.
